Types of Energy

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, chemical, and electrical.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. For example, an object at a height has gravitational potential energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released during a chemical reaction.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices and can be converted into other forms of energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object. It is the energy associated with the motion and position of an object.

Front

What is an example of chemical energy?

Back

A battery stores chemical energy that can be converted into electrical energy.

Front

What happens to energy in a battery when it is used?

Back

A battery transforms chemical energy into electrical energy when it is used.
